Although somewhat neglected now, at the height of his fame Ernest Bramah's mystery tales appeared alongside Sir Arthur Conan Doyle's Sherlock Holmes stories in the Strand Magazine, even occasionally outselling them. First published in 1913, 'The Knight's Cross Signal Problem' was one of his popular tales. Many crime and detective stories, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
